VIMPROVEMENT IN VAPOR-BURNERS.

Spccilicaiion forming part of Letters Patent No. 1015.528. dated October 1S, IS7

To all whom, it may concern,.-

Be it known that I, CHARLES E. SMITH, of Columbus, in the county of Franklin and State of Ohio, have invented certain Improvements in Vapor-Burners; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

My improvements relate to vapor-burners in which the oil or luid is contained in avessel or chamber, or in any ordinary house-lamp, below the burner 5 and it consists in peculiarities of construction of the wick-tubey and of the tip which surmounts such tube.

Figure l is a view of my invention applied to a glass lamp, the wick in place and lamp burning; Fig. 2, a vertical section of the burner-tube and its tip, and also of the screw-cap of a'lamp affixed tothe tube; Fig. 3, an enlarged view of the top of the wick-tube, showing the orifices for emission of the gas.

A is a glass or metal vessel of any ordinary construction, such as is used for common oillamps.

B is a wick-tube adapted to be screwed or fastened to the vessel in any well-known manner, but instead oi' being open at top to allow the wick to pass through, as in old styles of lamps in which the wick is ignited, the top is closed, as seen at b, so that the wick is confined therein, and is never designed to be set on fire. In the top of this tube are made two very minute orifices, l l, for the emission of the vapor generated from the fluid. These openings are at their upper or oulet side almost invisible, and they are preferably made slightly divergent, so that the streams of gas discharged therefrom shall slightly diverge, from each other. Instead of two, one opening may be employed, or several.

C is the tip, the lower part, c, of which is tubular, and of a diameter suiiicient to go snugly over the top of the wick-tube, so that it will hold its position and yet allow of being readily removed for the purpose of cleaning, if need be, the several parts, or for any other purpose, a proper stop or ridge within the tiptube preventing the wick-tube from entering too far within the tip-tube. The portion of the tip marked d, and which is above the oriiices l 1., is made of somewhat larger diameter than its lower portion and provided, as seen at e e, with air or oxygen holes for the admission of atmospheric air from without,l to supply oxygen to commingle with gas as the latter is generated and discharged from the orifices l 1.

The part d is provided, as seen at f f, with two converging walls, which are planes inclined at equal angles-say about forty-five degreesto the sides of the tube, of which sides they form a continuous part; but these parts f f do not meet, a narrow straight space being left between them for the illuminatingiiame. A space, g, is cut away on opposite sides of the tip, as seen. This space is made wide, to give free outward passage to the flame. The vapor emitted from the opening or openings l strikes or comes in contact with the inner faces of the inclined iiatsides ff ofthe tip, and while all that is needed to feed the eentral portion of the iiame is free to rise in a thin sheet through the narrow space, or slit at the top, yet the bulk of the vapor, by reason of its striking against the inner inclined surfaces, is arrested and prevented from passing out at this top slit, and is deflected by such inclines, and seeks vent elsewhere. The larger volume so seeking vent is forced out laterally, and needs larger outlets at the side than the thin sheet required at the top, and to compel these side outlets to deliver properly at their lowest parts,'and thus produce the bzitwilig llame required, these outlets are made of graduallyincreasing width from the top slit downward, thus securing a greater lateral exit at the bottom of the outlet. This, so far as I am aware, is the only instance in which this desirable and popular bat-wing llame has ever been produced in a self-generating vapor-bnrner.

The adaptation of my peculiar burner and tip combined to an ordinary hand-lamp renders it especially valuable for household purposes, as yielding a brilliant llame, and at the same time having thefluid all beneath the ilanie, as in ordinary oil-lamps, thus conducing to safety and preventing all possibility of overflow or dangers arising therefrom.

It will be understood that that 'portion of the wick not confined within theltube remains within the body of the reservoiror;lamp immersed in the iluid, and that the fluid is raised into the tube by eapillaryattraction.

I claiml. A vapor-burner tip constructed with two inclined sides nearly meeting1 in a straight line in the burner and is closed at its top, With the at the top, and diverging downward from each exception of it minute outlet or outlets thereother on their inner faces, and having lateral in, as and for the purpose described. outlets converging upward, as shown atff g, r

all as and for the purpose set forth. CHAS E' SMITH 2. In combination with ai burner constrnet- Witnesses:
